No one can study with an empty stomach. You need at least fulfil their food needs or every man capable of working will be sent to the field. If the government can erase poverty, the citizen can start to look at other than fulfilling basic life needs like education.
Enough food is also needed for brain development. Poverty in neonates and child can cause impaired intelligence later in their life.
I'm going to use the US government organization with such authority. The FDA or Food and Drug Administration has the power to recall food or drugs that pose a health risk to the population. This is usually the minimum upper power after the company, which will usually initiate so as to keep from litigation.
It is still flat but the city air and gas may be more perception
I'd like to say Anger should be the answer. Stroke's and Heart disease are relatively prone to worsening due to massive amounts of stress, while TMJ which is the degeneration of the joints of the mandible are prone to said degeneration when reactions to stress like grinding or clenching the teeth are done often.
Anger is more an emotion and is referred to as such. If Chronic Anger was an option used, then I'd go with TMJ.
